Cryogenics

At this forum, you will learn:

how low temperatures are achieved in different refrigerator types and how such refrigeration loops are balanced thermo-dynamically

which cryogens and materials are used in cryogenics

how to efficiently cool components such as superconductive magnets and which heat transfer characteristics should be considered when using helium

which types of insulation are best at which temperature level and depending on the heat generated

aspects to consider for the construction and specification

which sensors can be used at low temperatures and what kind of control circuits have proven their worth in cryogenics

which dangers can arise in dealing with cryogens

FORUM CHAIRMAN

This cryogenics information and further training forum is now in its 39th year. During this time, cryogenics has increased in importance and is increasingly used in many spheres.

This forum imparts a technical introduction: Thermodynamic basics of refrigeration Industrial techniques of refrigeration (liquefaction,

refrigeration units, cryocoolers) Thermodynamic properties of cryogens Aspects and techniques of cryogen logistics Basics and techniques for heat transfer to cryogens and

for thermal insulation Design techniques and process engineering for the layout

of cryogenic-systems and basics and techniques of cryo-genic temperature measurement and control circuitsSafety aspects and safety provisions for handling cryogens

The following topics concern today’s and future large-scale applications in cryogenics: Helium refrigerators and liquefi ers Superconducting high fi eld magnets Cryopumps Hydrogen as an alternative fuel
